7 Claims.

An object of my invention is the provision of a` gas burner having a plurality of outwardly extending conduits or jets fed by gas through a plurality of openings formed by a slotted disk seating between two members which when fitted together define the outwardly extending conduits orJ'ets.

Another object of my invention is the provision of air intake openings for the conduit means or jet in which the openings are adjusted as to their size to vary the mixture of gas and air.

Another object of my invention is the provision of admitting the flow of gas into a plurality of outwardly extending conduits or jets and of mixing the air with the gas in the conduits or jets, whereby the burner is capable of producing a blue or heating flame even when the gas supply is cut down to a very lowpressure.

Another object of my invention is the provision i' a gas burner which is simple and inexpensive to manufacture and in which several parts can be readily assembled and also changed so as to vary the amount of gas admitted to the plurality of outwardly extending conduits or jets. Other objects and a fuller understanding of my invention may be had by referring to the following description and claims. taken in conjunction with the drawings, in which:

Figure 1 is a top plan view of a burner embodying the features of my invention;

Figure 2 is a vertical cross-sectional view of my gas burner taken along the line 2-2 of Figure 1;

Figure 3 is a cross-sectional view taken along the line 3-3 of Figure 2;

Figure 4 is a cross-sectional View taken along the line 4-4 rof Figure 2;

Figure 5 is a view of the underneath side of T extending outwardly therefrom, a conical annul'ar member I5 fitting in the conical annular iiange I4, and a disk II seated between the conical annular flange I4 and the conical annular member I5. The tubular member I2 and the attachment coupling I I have interiitting shoul- My burner comprises generally a tubular ders at 32 for making a gastight connection therebetween when the burner is assembled by means of a connecting bolt 22 which threadably engages a' central lug 23 constituting a part of the attachment ycoupling II. Surrounding the central lug 23 are a plurality of openings 24 through which the gas Hows ,upon leaving the gas supply pipe I0.

` The upper end of the tubular member I2 flares outwardly and is provided with a distributing outlet end I3 across which the disk I1 extends.

The marginal edge of the d'sk II is indicated by the reference character I8 and is provided with a plurality of outwardly extending slots I9. The marginal edge portion I8 oi the disk I I is seated between the outlet end I3 of the tubular member' I2 and a peripheral edge portion 33 of the conical annular member I5, whereby the slots in the disk provide a plurality of openings through which the gas may flow.

The conical annular member I5 constitutes a. closure means for the outlet end I3 of the tubular member I2. The conical mating surfaces of the conica1 annular iiange I4 and the conical annular member I5 are respectively provided with semi-circular ,grooves 30 and 3| which when the two anges are secured together by the connecting bolt 22 provide a plurality of conduits or jets for the gas. The slots I9 in the disk I1 are in alignment with the conduits or jets, whereby the slots in the disk provide a plurality of openings through which the gas passes upon leaving the outlet end I3 of the tubular member I2 and upon entering the conduits or jets. The slots of the disk may be held in alignment with vthe conduits or jets by any suitable means and as illustrated in Figure 3 the central portion 0f the disk I I is provided with a triangular opening 20 which ts over a triangular boss 2l on the underneath side of the conical annular member I5 whereby the disk cannot turn after it is once mounted in position. When the connecting bolt 22 is turned down tight the two conical flanges fit tight against each other to define the conduits or jets without any clearance between the mating surfaces. The peripheral edge Dortion 33 of the conical annular' ange I5 which seats or makes engagement against the marginal edge portion I8 of the disk may be slightly recessed to receive the disk whereby the two flanges may make a tight t therebetween when the connecting bolt 22 is turned down tight. The amount of gas which flows through the slots in the disk may be determined by the thickness of the disk. For burners which require a. small are alternately of dierent lengths. conduits or jets areindicated by the reference assente d amount of gas the disk may be of relatively thin sheet-like material and for burners requiring a considerable amount of gas the disk may be made of thicker material. In my invention the seated recess provided in the conical annular member I5 may be made to receive the disk of the thinnest dimension and for thicker disks a slight clearance may be present between the two annular fianges when the connecting bolt 22 is turned down. In my invention the outer edge of the anged members are arranged to contact first so that when a. thicker disk is used the small clearance or crack which appears'between the flanges is present only in the region near the disk and there nwill be no clearance or crack between the mating flanges at the mouth of the conduits or jets, The dierence in the thickness of the disk to regulate the amount of gas flow may be only in the neighborhood of a few thousandths of an inch so that when a thicker disk is used the clearance between the two anges in the locality i adjacent the disk is only in the neighborhood of a few thousandths of an inch.

As illustrated in Figurev 2 of the drawing, the bottom or the throat end of the conduits or jets is provided with air intake openings 34. The amount of air which flows into the air intake opening 34 is regulated by an air adjusting sleeve 35 having a conical flange 36 which iits against the underneath side of the conical annular flange I4. 'Ihe conical ange 36 is provided with a plurality of air adjustment holes 31 and the alignment of the air adjustment holes 31 with the air adjusting or intake opening 34 regulates the amount of air admitted to the conduits or jet openings. 'When the conical ange 36 is properly adjusted the adjustment may be maintained in a xed position by operating the set screw 38 which holds the air adjusting sleeve and conical flange in a fixed position. The mixture of the gas and air determines the nature of the flame and when adjusting the amount of air the operator observes the nature of the ame and when the llame is of the proper kind the set screw 38 is then set to maintain the s adjustment.

In Figure 6 I show a modication of the air intake adjustment in that the conical annular member I5 is provided with air intake openings 4I which are adjusted as to size by the air adjusting plate 42 held in a fixed position by the connecting bolt 22. The air adjusting plate 42 has a. conical ange 43 and the conical ange is provided with a plurality of air adjusting holes 44 which when properly aligned with the air intake openings 4I determine the amount of air admitted to the conduit or jet opening and thereby regulating the nature of the flame.

In the drawings, I have illustrated the conicaln annular flange I4 and the conical annular member I5 as being made of castings but it is also understood that these two parts may be made of stamped material, which when the two parts are secured together denne outwardly extending conduits or jets. In order to distribute the flame emitting from the conduits or jets the conduits The long character 25 and the short conduits or jets are indicated by the reference character 26, and these are alternately disposed around the burner. As

shown in IEigurey 6, the ends of the conduits or jets are provided with upwardly directed baiiles 45 for directing the flame upwardly. The bailles are integrally formed with the conical annular ange ii and may be at any suitable anglefor directing the names as they leave the conduits or jets. v The bames may also be applied to the burner shown in Figure 2.

Although I have described my invention in its preferred form with a certain degree of Aparticuiarity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
